Description

Technical Field

[0001] This utility model relates to the field of electric bicycle technology, and in particular to a conductive structure for a battery box. Background Technology

[0002] In battery-powered devices, the conductive structure of the battery compartment is a key component for achieving power transmission. Traditional battery compartment conductive structures typically employ a split design, including a male connector and a female connector, with circuit conduction achieved through the insertion of these two components. However, in existing technologies, the conductive terminals of the male connector are often composed of multiple independent conductive plates, which need to be fixed and electrically connected by soldering.

[0003] While this welding method can meet conductivity requirements to a certain extent, it presents several problems in practical applications. First, the welding process is complex, increasing production costs and making it prone to poor welding leading to increased contact resistance and affecting conductivity. Second, the welded joints may experience fatigue fracture during long-term use, resulting in unstable connections or even open circuits, reducing product reliability. Furthermore, the welding process requires highly skilled operators, hindering large-scale automated production. Utility Model Content

[0023] like Figures 1-2 As shown, this embodiment of the utility model provides a conductive structure for a battery box.

[0024] A conductive structure for a battery box includes a male connector 1 and a female connector 2. The male connector 1 includes a first insulating shell 3, a first terminal 4, and a second terminal 5. Both the first terminal 4 and the second terminal 5 include a first conductive connecting piece 6, a second conductive connecting piece 7, and a connecting strip 8. The two ends of the connecting strip 8 are respectively provided with a first bending portion 9 and a second bending portion 10. The first bending portion 9 and the second bending portion 10 are respectively connected to the top of the first conductive connecting piece 6 and the top of the second conductive connecting piece 7. The first conductive connecting piece 6, the second conductive connecting piece 7, and the connecting strip 8 are integrally formed. The female connector 2 includes a second insulating shell 11 and a plurality of conductive springs 12. The conductive springs 12 are all disposed inside the second insulating shell 11. The first conductive connecting piece 6 and the second conductive connecting piece 7 are respectively disposed corresponding to the conductive springs 12.

[0025] This invention integrates the first conductive connecting piece 6, the second conductive connecting piece 7, and the connecting strip 8 into a single unit, eliminating the welding steps required in traditional structures. This not only reduces production costs but also improves production efficiency, facilitating automated mass production. It also enhances the overall structural stability and ensures excellent electrical contact performance. The integrated conductive structure reduces intermediate connection points, lowers contact resistance, and improves current transmission efficiency, thereby guaranteeing stable power output. It is suitable for equipment such as electric bicycles that require high conductivity. Furthermore, it avoids circuit failures caused by welding defects or weld fatigue fracture, significantly improving the overall reliability and service life of the product.

[0026] In the conductive structure of the battery box described in this embodiment, a first wire pressing part 13 is provided on the rear side of the first conductive connecting piece 6. Specifically, by providing the first wire pressing part 13 on the rear side of the first conductive connecting piece 6, the wires can be directly pressed and fixed on the conductive connecting piece, avoiding the use of traditional welding methods for wire connection. This not only improves the reliability of the connection but also reduces the problem of increased contact resistance caused by poor welding, thereby improving the safety and assembly efficiency of the overall structure.

[0027] In this embodiment, a conductive structure for a battery box is described. The first bent portion 9 and the second bent portion 10 are respectively connected to the top rear end of the first conductive connecting piece 6 and the top rear end of the second conductive connecting piece 7. The first conductive connecting piece 6 and the second conductive connecting piece 7 are arranged parallel to each other, and the connecting strip 8 is arranged perpendicular to both the first conductive connecting piece 6 and the second conductive connecting piece 7. Specifically, this structural design arranges the first conductive connecting piece 6 and the second conductive connecting piece 7 in a parallel layout, while the connecting strip 8 is arranged perpendicularly, forming a stable U-shaped structure that enhances the overall structural strength of the terminal. Simultaneously, the bent portion is located at the top rear end of the conductive connecting piece, which helps improve the stability of the insertion and removal engagement between the terminal and the conductive spring 12 of the female connector 2, thereby improving the reliability and service life of the conductive connection.

[0028] The conductive structure of the battery box described in this embodiment further includes a third terminal 14 in the male connector 1, which is disposed between the first terminal 4 and the second terminal 5. Specifically, the addition of the third terminal 14 between the first terminal 4 and the second terminal 5 expands the functional interface of the battery box conductive structure, which can be used for signal transmission or to achieve multi-channel power supply, meeting the multi-functional connection needs of devices such as electric bicycles, while maintaining a compact overall structure and improving the applicability and integration of the connector.

[0029] In the conductive structure of the battery box described in this embodiment, a second wire crimping portion 15 is provided on the rear side of the third terminal 14. Specifically, this male connector 1 has wires only on both sides, and one of the wires is crimped with the second wire crimping portion 15.

[0031] The conductive structure of the battery box described in this embodiment includes a reinforcing portion 16 at the front end of the first insulating shell 3, within which the connecting strip 8 is located. Specifically, the reinforcing portion 16 at the front end of the first insulating shell 3, which accommodates the connecting strip 8, effectively improves the overall mechanical strength of the terminal assembly, prevents the connecting strip 8 from deforming or breaking due to external forces, thereby ensuring the stability of the conductive connection and extending the product's service life. It is particularly suitable for environments with frequent insertion and removal or vibration.
